device snapshot isn't visible/usable anymore

device snapshot isn't visible/usable anymore

Hello there
 
I work with the OP-Manager 8 (bild 8050) and has a small networkconfig @ work (11 Devices from our productline).
After updating from OP-Manager v7 to v8 the snapshots of the devices were not working anymore. In fact, I can click on a device an there's just a white window. Are there any corrput links after updating the OP-Manger and is it possible to correct these links in the current installation (without reinstall the OP-Manager - for example check or edit some of the conf-xml-files...)?
 
thx for your help & ideas
